Tiger doubling from 2010 aim review – Sumatra

Indonesia is a archipelago of islands. Once connected to the Asian mainland, animals were able to make their way along the peninsular. When sea levels rose in the ancient past they were marooned on the islands.

Once they were found on a few islands including Bali and Java. They are now only found Sumatra. Sumatra is thought to have 400 tigers in 2010. This is down from as many as 1000 back in 1978.

San diago zoo estimate the number remaining in the wild at 400-600, but I cannot find any reason for this higher band.

It is possible that the tiger population has increased a bit, but in certainly has not doubled.

The Tapanuli Orangutan is still threatened with extinction, despite only recently being discovered

The Tapanuli Orangutan lives on Sumatra but are thought to be more closely related to Bornean Orangutans. Numbering around 800 members, they had a far wider ranging habitat until recently. They are now restricted to about 1000 square km – about 2.5% of their former range.

While looking very similar to other orangutans, this sub species has not interbred with any other orangutans for over 1 million years and despite living in Sumatra, are more closely related to the Borneo Orangutan

What is harder, is that these Orangutans are not naturally mountainous animals, but have been driven there by the hunting that has so decimated their numbers.

Third Sumatran rhino sanctuary moving forwards

The Sumatran rhino is critically endangered. Just a few years ago, the last of the mainland Sumatran rhino died, leaving only the population on Sumatra itself.

This new sanctuary will be in the Leucer ecosystem, close to where the remaining wild rhinos live.

Much help is needed to reverse the enormous declines in this population which humans have caused – and if this help is not forthcoming in the next few years this ancient species will be lost for good.

It is a good move, but time will tell if it will be good for the Sumatran rhino and its future

Sumatra is building good motorways across the island leading to the photo of a Sumatran tiger on the edge of the new motorway

Workers building a motorway through the Sumatran rainforest got a beautiful shot of a tiger before it ran back into the forest. Due to the destruction of its home the Sumatran tiger is highly endangered so while this sighting is encouraging it also suggests that the continued building is further eating into the habitat that is left.

Unfortunately this road not only endangers local Sumatran tigers but also elephants.

Give carbon credits for a dam which requires a large area of rainforest to be cut down? That’s absurd.

Indonesia is pressing ahead with its desire to build a dam in the Sumatran rainforest. Now when the Dam is filled and floods this vast area of rainforest, all the carbon currently stored in the trees will be released back into the air- either as carbon or as meeting due to the breakdown of the wood under water. Calculations were made suggesting that this damn could take decades or even centuries to reach carbon neutral based on the amount of Carbon released when it is filled.

Dam that threatens the survival all of the rarest great ape is in the wrong place will make more carbon dioxide emissions during building and reduce emissions less than claimed

A recent analysis has shown that the the Dam that would cover 90% of the Tapanuli orangutan population has had the prospects of positive outcomes hugely hyped by it’s backers, and minimising negative facts about the Dam have been buried.

The region is already well connected to the grid with almost all Communities already served. Due to the astounding amount of Forest that would be lost if this damn were to be created, if it were to ever reduce carbon emissions it would take many decades if not centuries for the carbon cost of the dam to be offset by the electricity it creates. Given that in order to stop catastrophic climate change we need to be cutting carbon emissions now it will not help in this fight whatsoever.

The last Sumatran rhino living in Malaysia has died

The Sumatran rhino was once found throughout out much of Southeast Asia including parts of India, Vietnam, China, Myanmar, Thailand as well as Borneo.

Now that the last known Sumatran rhino living in Malaysia has died it is thought that the Sumatran rhino is extinct on mainland Asia. As you can see by the list of countries that was found in it was once relatedly widespread and its decline has been rapid. While there is still a population of perhaps 80 living in Sumatra, its rainforest is still being cut down the main reason it is so endangered now. As one of the most ancient rhino species it is important that we maintain those members that have left to be able to form founding populations in the countries that is been lost from.

Whether this happens is anyone’s guess, unfortunately though given the demand for rhino horn and the decimation of rhino populations in all the countries they are found it is not certain that this population will will survive.

Two more elephants found dead in Sumatra

The elephant populations of Borneo and Sumatra are highly important for the ecosystem they operate in. Unfortunately due to the human behaviour in the area their habitat is being cut up into smaller and smaller parcels of land. When they wander across unmarked arbitrary lines humans attack them.

New species of Orangutan

The Tapamuli Orangutan has recently been discovered. There are only thought to be 800 of these animals left and they are only found within the Batang Toru Forest of North Sumatra. It is thought that they have been a separate from the Borneon Orangutan for 674,000 years (despite living on Sumatra they appear to be more closely related to the Orangutans of Borneo than of Sumatra). As well as having such a tiny population they also live in an area of roughly 1000 square kilometres (386 square miles). This is the first great ape species to be discovered since 1929 when the Bonobo was discovered.
